1 Equipment anchor bolt design regulations
1.1 Scope of application
These regulations apply to the design of equipment anchor bolts in chemical plants. 1.2 Professional division of labor
1.2.1 The type, material, size and extension length of non-standard equipment anchor bolts shall be determined by the equipment professional according to the equipment drawing and installation location (see equipment layout drawing). The civil engineering structure professional shall design the equipment foundation. 1.2.2 The anchor bolts of standard equipment and rotating equipment shall generally be supplied by the equipment manufacturer. The equipment professional shall be responsible for providing the manufacturer's information.
1.2.3 For equipment on platforms and floors, the type and size of anchor bolts shall be determined by the three disciplines of pipeline, equipment and civil engineering through consultation, and the equipment discipline shall design and propose conditions. 1.2.4 The layout discipline shall propose equipment foundation conditions (see Chapter 2 of HG20546.4-92) and equipment support conditions on floors (or platforms) (see Chapter 3 of HG20546.4-92) to the structure discipline according to the equipment layout drawing and the requirements of this regulation, but not including anchor bolts.
1.3 Design requirements
1.3.1 All tower equipment shall use direct-buried anchor bolts with templates as much as possible according to specific requirements, and the templates shall be provided by the equipment manufacturer. If no template and direct-buried anchor bolts are used, a hole with a diameter larger than the bolt and a separate cover plate shall be left on the bottom plate: the cover plate of the bolt hole shall be welded on site after installation. This structure is also applicable to other non-standard equipment to avoid construction deviation and installation difficulties. 1.3.2 Orientation of anchor bolts For equipment on the ground foundation, according to the design of the general equipment layout, the centerline span is set in the north direction of 103
(the azimuth angle is 0°), and the number of bolts is a multiple of "4". When there are three legs of the equipment, the orientation of the legs should be determined according to the following regulations or according to the needs of piping. Pipe
[180°
Figure 1.3.2 Equipment 1 and 1 on both sides of the corridor have a 180° difference in orientation. Equipment III at the corner of the corridor is determined by the size of A and B. A is in the figure.A, then equipment II should be changed to equipment 1 leg orientation, equipment N is symmetrical with equipment.
1.3.3 For equipment and towers with vibration, double nuts should be used for anchor bolts. 1.3.4 When installing hook-type anchor bolts on the equipment foundation, the anchor bolt diameter and foundation reserved hole size are shown in Figure 1.3.4 and Table 1.3.4. Anchor bolts are in accordance with GB799-76. For anchor bolts with a diameter greater than M48, see the civil engineering professional data (TC60B2-82).

According to diameter × length
3500 × 30000 and above or any × 40000 and above 1800 × 10000 and above or any × 20000 and above Smaller than the above size
2.1.2 The preparation of equipment hoisting plan shall comply with the provisions of "Chemical Engineering Construction Hoisting Construction Code" (HGJ201-83), and is usually prepared by the construction unit. However, the technical conditions of the main equipment hoisting plan, such as the requirements for lifting ears and hoisting orientation, shall be jointly agreed with the construction unit. 2.1.3 For some equipment that may be replaced, sufficient space and passages should be reserved during the equipment layout design to facilitate the installation and disassembly of equipment and transportation. 2.1.4 Before the equipment layout design \D" version, it is necessary to understand the equipment status of the construction unit's lifting equipment and the conditions for outsourcing.
2.1.5 The requirements for equipment transportation outside the factory are limited to proposing the following contents to the project leader in order to consider the budget and solve transportation problems.
2.1.5.1 The name, number, overall dimensions (including pipe mouth), tonnage and main materials of over-limit equipment. 2.1.5.2 The name, number, size, tonnage and main materials of other equipment that need to be considered for transportation. 2.1.5.3 The overall dimensions should include the factory packaging dimensions (contact the manufacturer). 2.2 General requirements
2.2.1 The following items should be considered when transporting equipment from the factory warehouse or factory dock to the installation site: 2.2.1.1 The load-bearing capacity of the roads and bridges passed through during transportation 2.2.1.2 Whether the buildings, structures, overhead cables, pipe racks and other ground facilities along the way have an impact on transportation. 2.2.1.3 Whether the underground facilities and burial depth during transportation can withstand the pressure of the transported equipment. 2.2.1.4 When large equipment is transported directly to the site by water, the capacity of the lifting facilities used at the factory dock should be considered. 2.2.2 When the equipment is placed on a pallet (seat) after leaving the factory, the orientation of the equipment should be consistent with the installation orientation. 2.2.3 For equipment of extra-large size (such as spherical tanks, oil tanks, etc.), the manufacturer should provide prefabricated parts for on-site assembly on the equipment foundation.
2.2.4 The requirements for the hoisting plan for outdoor equipment without a frame that is directly installed on the foundation are as follows: 2. 2.4.1 The scheme adopted in the lifting design should take into account the machinery and equipment of the construction unit and the conditions for outsourcing. 2.2.4.2 For tall equipment, whether to adopt overall combined lifting should be decided by the construction unit: 2.2.4.3 Consult with the construction unit to decide on the equipment position number, lifting eye setting requirements, reserved space requirements, equipment number with lifting sequence requirements, etc. that are installed with a pole or movable lifting equipment. 2.2.4.4 The depth of the design scheme is limited to ensuring the possibility of lifting and the provisions of 2.2.4.3. As for the specific lifting plan, it should be prepared by the construction unit. 2.2.5 Use a winch to lift the equipment within the frame. 2.2.5.1 If the equipment located within the frame uses movable lifting equipment (truck crane, crawler crane), try to use this type of lifting when the lifting can be completed by extending the boom. When it is not suitable to use the above equipment for lifting, a tower crane can be used (if the conditions for a tower crane are available). At the same time, the order of frame construction and equipment lifting should be determined.
2.2.5.2 For equipment located in the frame, temporary beams can be set up on the top of the frame or on the floor higher than the equipment installation floor, and hoisted by a winch, and sufficient space height is required. At this time, a specific lifting plan should be made to find beams and plates that hinder lifting. The civil engineering specialty designs this part of the beams and plates to be movable, and determines the load of the frame according to the lifting plan, as shown in Example 6.
2.2.5.3 Leave holes on the floor. When lifting equipment with lugs, if the lifting method of passing through the floor from below is adopted, the size of the opening should be considered to be able to pass through the pipe opening and lugs of the equipment, and a movable beam should be set so that the lugs can be supported on the beam.
2.2.5.4 For particularly large equipment with skirt seats, the equipment can be installed in place first and then the civil engineering frame can be constructed. 2.2.5.5 For special large equipment supported on the floor, a temporary skirt can be installed on the equipment first, and the equipment can be installed on the temporary foundation. Then the civil engineering framework can be constructed. When it is confirmed that the ear surface on the beam can bear a certain load, the temporary support can be cut off.
2.2.6 There should be lifting holes in the factory or framework, and the equipment can be lifted by the lifting beam. When using the public lifting holes in the factory, if there is no crane, the following points should be noted when lifting the equipment: ·109
2.2.6.1 The size of the lifting hole should meet the requirements of the maximum equipment size (including the size of the outer edge of the equipment ear or bracket). The size of the building door should consider that the vehicle carrying the equipment or the equipment with the packaging bracket can enter the area of the lifting hole in the wide room.
2.2.6.2 There should be a lifting beam on the top floor, which can be used to hang a manual crane. 2.2.6.3 Whether the strength of the beam and hook of the lifting point meets the requirements of the maximum equipment load (including the weight of the rigging). 2.2.6.4 When the equipment is transported from the lifting hole of the building to the installation point and the temporary placement location, the loads (including horizontal forces) of the beams and slabs that it passes through should be calculated by the civil engineering professionals. 2.2.6.5 When the equipment enters the factory building from the outside of the wall, the wall should be built after the equipment is hoisted, and it should be stated in the design instructions.
2.2.7 When using a crane (bridge crane, electric hoist, etc.) to lift equipment in a factory building or frame, the following points should be noted:
2.2.7.1 Due to the width of the bridge frame and the travel of the lifting crane, the equipment arranged against the wall should be within the reach of the bridge crane's hook. 2.2.7.2 There should be no obstacles such as pipelines, cable trays, platforms, etc. in the lifting operation area. When the equipment is installed at the height of the floor, lifting holes should be provided. See the requirements of 2.2.6.1. 2.2.7.3
2.2.7.4 In order to consider the utilization rate of the floor, movable covers and movable railings can be added to the lifting holes that are not frequently used.
2.2.8 Crane selection and other precautions: 2.2.8.1 Crane selection requires reference Select the data in Table 7.3.1.1 of "Equipment Hoisting Conditions" (Chapter 7 of HG20546.4-92).
2.2.8.2 Has the lifting height taken into account the safe distance between the hook and the bridge and the distance from the crane hook to the ground? Does the crane's lifting capacity meet the requirements of the heaviest components and leave an appropriate margin? 2.2.8.3
Does the production environment have explosion-proof requirements, and is a crane with an operating room used? Is the crane span the same as the track pitch? Does the specification of the monorail beam meet the requirements of the monorail electric hoist? Figure 1 Plant equipment transportation route map
